Quality Control

Our Benzenamine, 2,3,4,5,6-Pentamethyl-, Conjugate Acid (9Ci) is produced under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing key specifications such as assay, impurity profile, and physical characteristics are provided and available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
